Intralobar sequestration of the lung in an adult (type 1 of pryce). Treatment by coil embolization

A 34 year old patient presented with recurrent hemoptysis. A chest radiograph was normal. Helical CT angiogram of the chest with tridimensional reconstructions demonstrated an intralobar pulmonary vascular sequestration Pryce I-type of the right lower lobe. The angiography confirmed the diagnosis showing a large feeding artery arising from the coeliac trunk. An embolization of the feeding artery using metallic coils was performed. Transient pulmonary infarction occurred immediately after treatment. At two years follow-up, the patient remains asymptomatic. Percutaneous embolization of this rare pulmonary vascular malformation is an alternative to surgical treatment.
